SPECIFICATION forming part of L etters Patent m; 502.904, dated Augusts, 1893.

Application filedl'anuary 18, 1893. Serial No. 45817542. (No model.)

To all whom it may con/067%:

Be it known that I, ISAAO Q. GURNEE, a citizen of the United States,residing at Butler, in the county of Morris, State of New Jersey, haveinvented certain new and useful' Im provements in a Combined Atomizerand Syringe; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skille'din the art to which it appertains to make and use the same, referencebeing had to the letters of' reference marked on the accompanyingdrawings, which form a part of this specification.

My invention relates to atomizers and syringes.

The improvements consist-in the following Construction and combinationof parts, which will first be fully set forth in detail and the featuresof novelty believed to be new then set forth and claimed.

Figure 1 represents an atomizer to which I have applied my syrin ge andatomizer combination attachment. Fig. 2 is a detailvertical sectionshowing the main operative parts of my invention. Fig. 3 is an endelevation of the valVe apparatus.

In the drawings-A represents an atomizer to which I have applied myinvention. This atomizer has been suitably modified in its constructionto adapt it to the purposes I have in viewthat is, the throwin g of asolid stream of liquid, or atomizing the same by introducing anair-blast therein; besides graduating the supply of air to be dischargedin connection with the liquid to any desired Volume, from the maximumdischarge to the entire shutting off of the same.

tube leading therefrom to th air tube D.'

As ordinarily constructed aportion of the air forced into the tube Dgoes downwardly into the vessel B to exert a pressure upon the fluidcontained therein for the purpose of forcing it up through the liquidtube C, and a part of the air pressure proceeds upwardly through thetube D, eXterorly of the tube O to the tip E where it meets the supplyof liquid from 'the vessl and atonizes it, producing a fine spray; Forthe purpose of converting such a construction so it will have theproperties of a,

tube'D, and'it also has a milled thumb-piece J rigidly attached thereto,by means of which the screw-sleeve I is moved in or outso as to cover oruncover the passage K, or to adjust it to any intermediate position oversaid pas sage. a..

L is an opening in line with the sleeve I, the two communicating in allthe adj ustments of the sleeve.

M isa bushing-stopper which effectually acts to cut off anycommunication of' the air pressure from the bulb F upwardly through thetip, except as hereinafter noted.

In the relative position of the parts shown in Fig. 2 my invention isadjusted for use as a syringe. All the air forced into the devicethrough the pipe G passes through the opening L and down into the'Vessel D for the purpose of ejectinga solid stream, the air passagebeing cut off and the bushingM preventing any flow of air whatever outthrough the air tube D When it is desired to change the syringe action'to that of an atomizer the thumb-piece J is turned in order that theinner end of the sleeve I may uncover the air passage K, therebypermitting a portion of the air to operate upon the liquid in the vesselB, and the balance to pass up through the passage K into the upper airtube D for the purpose of atomizing the fluid at the tip E.

For the purpose of graduating the amount of air which may be allowed toescape up the passage K, I provide an' annular dial-face N having aseries of graduating marks the'reon-- as shown in Fig. 3--in conjunction with which a pointer mark O on the thumb-piece J, is made toregister. When the pointer O is in line with the scale-mark S the sleeveI is d I Sleeve I has a lengthwise adjustment in theopening provided forit in the IOU at the limit of its inward movement, and the air passage Kis entirely shut off-see Figs. 2 and 3. When it is desired to open upthe communication with the air passage K the thunb piece .I is turned tothe left to such a degree as will open the passage K to any degreedesired in order to let more or less air into the upper tube D. I mayestablish certain marks upon the scale-face N, with which the point Omay register, as will indicate that the air is entirely shut off fromthe passage K, or is fully on; or is at any predetermined point betweenthe two. The scale-piece N is rigidly attached to the tube D in anysuitable way, after it has been properly adj usted thereon, and apacking P is interposed between the sleeve and the scale-piece toprevent any leakage of air between the two.

All the main Operating parts are preferably made of hard rubber, and inorder to introduce the air passage K a removable bushing or sleeve Q isintrodued into the tube D, which permits the passage K to be madetherein before the bushing Q is inserted.

I have described one way in which my 00111- bined syringe and atomizermay be constructed. It should be understood however that my invention isbroader than the particular structure herein shown and described.

I may embody my invention in structures other than the one herepresented and still come within the spirit of my invention.

I claim-- l. The combination of an air pipe, an adjustable sleevelocated therein having a thumb-piecc, and a seale-piece upon the airtube.

2. The combination of a liquid tube, an air tube concentric with theliquid tube, an air supply tube leading the'eto, and a plug orstop-sleeve slipped upon the liquid tube above the air-supply tube,adapted to close air-tght the passage through the air tube.

3. The combination of aliquid tube, an air tube, a supply tube leadingto the latter, a stop in the air tube above said supply tube, and achannel com municating with said air tube above and below the stop.

4. The conbination of a liquid tube, an air tube a supply tube leadingto the latter, a stop in the air tube above said'supply tube, a channelcommunicating with said. air tube above and below the stop, and a valvein said channel.

5. The combination of a liquid tube, an air tube concentric with theliquid tube throughout the length of the air tube, a bushing or sleevewithin the air tube concentrc with both the liquid and air tube, andhaving a port therein, and a channel leading from the air tube to saidport.

li. The combination of a liquid tube, an air tube, having an air-su pply connected thereto, and a sleeve in the latter havingalengthwisemovement for graduating the connection between the air and supply tubes.

7. The combination with a liquid tube, an air and an air-supply tube, ofa scale upon the supply tube, a rotary valve in the supply tube, and apointer or index upon the Valve adapted to traverse the scale.

8. The combination of an air supply tube, a liquid tube, an air tube, abushing or sleeve within the air tube and outside the liquid tube, andconcentric with both the air and liquid tubes, said bushing having anaxial opening therethrough and a lateral opening therein, the latterconmunicating with the air-supply tube.

In testimony whereof I affix my signature in presence of two witnesses.
